Correct Answer: B

Rationale: Clozapine is an atypical antipsychotic medication primarily used in the treatment of schizophrenia. One of the positive effects of Clozapine is the reduction of psychotic symptoms experienced by the patient, such as hallucinations (not hearing loss). Clozapine is effective in managing both positive symptoms (hallucinations, delusions, disorganized thinking) and negative symptoms (apathy, social withdrawal, lack of motivation) of schizophrenia. It is known for its efficacy in reducing hallucinations and other psychotic symptoms, helping the patient to lead a more stable and functional life.

Correct Answer: C

Rationale: When a patient expresses concern about a medication looking different from what they had taken before, it is crucial for the nurse to verify the original prescription to ensure that the correct medication is being administered. Checking the original medication prescription will help the nurse confirm if there have been any changes or errors in the medication orders. This step is essential for patient safety and to prevent any potential medication errors. It is important to prioritize patient safety and well-being in such situations, and verifying the prescription is the appropriate action to take in this case.

Correct Answer: A

Rationale: Of the options provided, documenting objective, observable findings such as large bruises on the thigh upon assessment is the most defensible entry in court. This type of entry is based on the nurse's direct observation and assessment of the patient's physical condition, which can be corroborated by other healthcare providers or evidence. It provides clear, factual information without making assumptions or subjective judgments. In court, this type of documentation can help support the nurse's credibility and reliability as a witness.

Correct Answer: D

Rationale: Before initiating any oxygen therapy, it is crucial for the nurse to first assess the patient's condition. This step allows the nurse to determine the patient's oxygen saturation levels, respiratory rate, lung sounds, and overall respiratory status. Understanding the patient's baseline condition helps in selecting the appropriate oxygen delivery method and flow rate that will best meet the patient's needs. Additionally, assessing the patient's condition allows the nurse to monitor the effectiveness of the oxygen therapy and make any necessary adjustments throughout the treatment process. Therefore, assessing the patient's condition is the necessary first step in providing safe and effective oxygen therapy.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.
